Results: In the present study blood pressure changes in 400 pregnant women were studied throughout their pregnancy in
different trimesters. Among 400 pregnant women under study, 352 women remained normotensive throughout their pregnancy
and 48 women developed hypertension during pregnancy. A signifi cant difference in blood pressure between women with
hypertension in pregnancy and normotensive pregnant women can be observed since the fi rst trimester, much before the actual
clinical diagnosis of hypertension in pregnancy.
